Answer:
Find the LCD of the first two, then the LCD of that and the third one.
Step-by-step explanation:
You can do it by finding the LCD of two of the denominators, then the LCD of that and the third denominator.
Or, you can factor each of the denominators and find their LCM by multiplying the unique factors to their highest powers.
___
<u>Example:</u>
1/21 + 1/35 + 1/45
The LCD of 1/21 and 1/35 is (21·35)/5 = 105. The LCD of 1/105 and 1/45 is ...
(105·45)/15 = 315
__
Using factoring ...
- 21 = 3·7
- 35 = 5·7
- 45 = 3²·5
LCD = 3²·5·7 = 315
Answer:
The answer is - 28 plus 16 and 12 together and u get 28 but bc there is a - beside 12 u put that in beside the 28
Answer:
Hi.
Step-by-step explanation:
Because this question is asking how much water the water tower can hold, it's asking for the volume of a cylindrical figure. Let's use this formula:
V
=
π
r
2
h
First, let's find our variables by plugging in our information.
r
=
(
1
2
)
d
r
=
(
1
2
)
20
r
=
10
h
=
24
V
=
π
(
10
2
)
(
24
)
Following PEMDAS (Parentheses, Exponents, Multiply, Divide, Add, Subtract), we'll find
(
10
2
)
first.
V
=
π
(
100
)
(
24
)
Now, multiply (100) and (24):
V
=
π
(
2400
)
V
=
2400
π
f
t
3
, or
~
7539.8
f
t
3
It is 2 19/100, because the two is 200%, and the 19 is a prime number. hope this helps
